Abstract: Highlights•Practical distribution planning in S&OP contains time-varying demands and costs.•It is formulated as a capacitated dynamic-demand JRP with time-varying costs (CDJRP-TC).•A three-phase solution method combining optimization and simulation was proposed.•The proposed method solved CDJRP-TCs 12 times faster than conventional approaches.•Its capability to obtain appropriate plans for cost increase rates was investigated.
